    • A stirring device for the electrolytic solution in a storage battery. A solution circulating tube having open opposite ends is disposed in the electrolytic solution. The open top opens to a gas reservoir having an inverted J shape and opening downward in the upper part of the solution. A gas collecting chamber collects gas bubbles generated by the electrode plates and this gas enters an inverted U-shaped siphon strap which opens at one end to the chamber and at the other end to the tube via a small hole in the tube at a middle portion thereof. The gas in the siphon strap forces solution and gas from the upper part of the tube and gas reservoir into the upper part of the electrolytic solution via the gas reservoir opening.
    • 一种用于蓄电池中的电解液的搅拌装置。 在电解液中设置具有开口相对端的溶液循环管。 敞开的顶部通向具有倒置J形并且在溶液的上部向下开口的储气罐。 气体收集室收集由电极板产生的气泡,并且该气体进入倒置的U形虹吸管带,其一端在腔室中开口,另一端通过管中的一个小孔在中间部分开口 其中。 虹吸带中的气体通过气体储存器开口将溶液和气体从管的上部和气体储存器压入电解液的上部。

    • An image data processing apparatus includes a converter for subjecting each block to a discrete cosine transform (DCT) to convert blocks into DCT coefficients, a first memory for temporarily storing the DCT coefficients, a second memory for storing threshold values of a quantization matrix which is used for quantizing the DCT coefficients, a quantizing part for quantizing the DCT coefficients, a differential part for obtaining a difference in D.C. components of quantized DCT coefficients related to present and previous blocks, a zero detector for detecting whether or not A.C. components of the quantized DCT coefficient are zero coefficients, a counter for counting a number of successive zero coefficients of the A.C. components, a coder for subjecting the D.C. and A.C. components to a Huffman coding to output a coded D.C. and A.C. components, a first register for storing an address of an arbitrary DCT coefficient, a comparator for comparing an address where the DCT coefficient is stored in the first memory and the address in the first register, and a second register for holding the DCT coefficient output from the converter when the two compared addresses match.
